## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.

  - Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it.
  - 1 of 32 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.

  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 532 tokens (~76/item across 7 items; 7 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 87/100
  - Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (7)

### `validate_vat` (~109 tokens)

Validate an EU or UK VAT number via VIES/HMRC.

Returns validity, registered company name and address where the member
state exposes them (Germany and Spain never do), a confidence level, and
the upstream source. Accepts the number with or without country prefix
(e.g. "DE123456789" or "123456789" + country_code="DE"). Greece: EL or GR
both work.

Input parameters:

- `country_code`
- `vat_number` (string, required)

### `validate_iban` (~53 tokens)

Validate an IBAN (offline MOD-97 checksum) and resolve the bank name and BIC.

Covers all SEPA countries. Accepts the IBAN with or without spaces.

Input parameters:

- `iban` (string, required)

### `validate_eori` (~39 tokens)

Validate an EORI customs number (EU via EC, GB via HMRC, XI for Northern Ireland).

Input parameters:

- `eori_number` (string, required)

### `lookup_company_by_lei` (~38 tokens)

Look up company data (legal name, address, status) by LEI via GLEIF.

Input parameters:

- `lei` (string, required)

### `lookup_company_by_vat` (~54 tokens)

Look up company data by VAT number (GLEIF cross-reference).

Useful as a fallback for German/Spanish VAT numbers where VIES returns no
company name/address by law.

Input parameters:

- `vat_number` (string, required)

### `get_vat_rates` (~43 tokens)

Get current VAT rates (standard/reduced) for an EU country by ISO 3166-1 alpha-2 code.

Input parameters:

- `country_code` (string, required)

### `check_service_status` (~63 tokens)

Check live health of upstream government services (VIES per-country, EORI, HMRC, GLEIF).

Public endpoint — works without an API key. Use it to explain why a
validation returned reduced confidence (e.g. Germany's VIES endpoint down).
